What is the Wago 857-815?
Short description:
WAGO's loop-powered RTD temperature signal conditioner records sensors (Pt100, Pt200, Pt500, Pt1000) and resistors up to 4.5 kΩ, converting the temperature signal into a standard analog signal at the output.
The loop-powered RTD temperature signal conditioner provides safe isolation between input and output with 3 kV test voltage per EN 61010-1.
Features:
No additional supply voltage required
For Pt100, Pt200, Pt500 and Pt1000 sensors, as well as resistors up to 4.5 kOhm
2-, 3- and 4-wire connection technology
Calibrated measurement range switching
Detects a sensor wire break/short circuit
Specifications
Notes
| Safety Information | The signal conditioner must only be configured with the DIP switch in the de-energized state. |
| Note | Use shielded signal cables!Only use shielded signal cables for analog input and output signals.This ensures the device maintains its specified accuracy and immunity to interference, even when external disturbances affect the signal cable. |
